It combines a contactor pair, a thermal bimetallic overload relay (Class 10), and a magnetic short-circuit trip in one package — meaning you get forward/reverse control and motor protection without wiring separate components. This is a current-production part, so you're not hunting surplus or a cross-reference. ## Duty ratings and what they mean for the panel That's the motor-switching capability — the contactor pair handles reversing duty, so the full load current at 400 V is about 1.6 A, and at 600 V about 1.3 A. The supplied contactor is a 3RT2023-1BB40, the link module is 3RA2921-1BA00, and the busbar adapter is 3RA2922-1AA00. The circuit-breaker size is S00, so the whole assembly fits a compact footprint: 90 mm wide, 130 mm deep, 265 mm tall. Clearance requirements: 30 mm above, 10 mm in front, 10 mm below, 9 mm at the sides. ## Snap-on DIN rail, vertical mount, pollution degree 3 Pollution degree 3 means it's rated for industrial environments where conductive dust or occasional condensation can occur — no need for an additional enclosure in a typical panel. The 24 V coil is standard for control circuits in most industrial panels.","metaTitle":"Siemens 3RA2220-1AB23-0BB4 SIRIUS Motor Starter, 690 V","metaDescription":"Siemens 3RA2220-1AB23-0BB4 SIRIUS non-fused reversing motor starter, Size S0, 690 V AC-3, Class 10 thermal overload, snap-on DIN rail.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"130 mm","Width":"90 mm","title":"3RA2220-1AB23-0BB4","Height":"265 mm","Upwards":"30 mm","Forwards":"10 mm","Backwards":"0 mm","Downwards":"10 mm","Trip Class":"CLASS 10","At The Side":"9 mm","Rated Value":"24 V","description":"Combination Starter Reversing FLA Range 1.1-1.6A 3 Pole 24VDC Coil S0 Open Type 1NO <(>&<)> 1NC Aux","During Storage":"-50 ... +80 °C","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-55 ... +80 °C","Fastening Method":"snap-on fastening on 35 mm DIN rail","Mounting Position":"vertical","Product Brand Name":"SIRIUS","Type Of Assignment":"2","Degree Of Pollution":"3","Product Designation":"non-fused motor starter 3RA2","Size Of Load Feeder":"S0","at 230 V rated value":"0.1 hp","at 400 V rated value":"550 W","at 480 V rated value":"1.6 A","at 500 V rated value":"550 W","at 600 V rated value":"1.3 A","at 690 V rated value":"1 100 W","Design Of The Product":"reversing starter","at 460/480 V rated value":"0.75 hp","at 575/600 V rated value":"0.75 hp","Of The Supplied Contactor":"3RT2023-1BB40","Of The Supplied Link Module":"3RA2921-1BA00","Size Of The Circuit-Breaker":"S00","at AC-3 rated value maximum":"690 V","Design Of The Overload Release":"thermal (bimetallic)","Of The Supplied Busbar Adapter":"3RA2922-1AA00","Design Of The Switching Contact":"electromechanical","Operating Frequency Rated Value":"50 ... 60 Hz","of the supplied RH assembly kit":"3RA2923-1BB1","Design Of The Short-Circuit Trip":"magnetic","Of The Supplied Circuit-Breakers":"3RV2011-1AA10","Product Extension Auxiliary Switch":"Yes","holding power of magnet coil at DC":"5.9 W","Surge Voltage Resistance Rated Value":"6 kV","Number Of Poles For Main Current Circuit":"3","Product Function Short Circuit Protection":"Yes","number of NC contacts for auxiliary contacts":"2","number of NO contacts for auxiliary contacts":"2","shock resistance according to IEC 60068-2-27":"6g / 11 ms","Of The Supplied Standard Mounting Rail Adapter":"3RA2922-1AA00","at 400 V according to IEC 60947-4-1 rated value":"153 000 A","operational current at AC-3 at 400 V rated value":"1.5 A","Type Of Electrical Connection For Main Current Circuit":"screw-type terminals","Mechanical Service Life (Operating Cycles) Of Contactor Typical":"10 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"20.8 A","insulation voltage with degree of pollution 3 at AC rated value":"690 V","Type Of Connectable Conductor Cross-Sections For Main Contacts Stranded":"1 ... 10 mm², 2x (2.5 ... 6 mm²)","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"1.1 ... 1.6 A","Connectable Conductor Cross-Section For Main Contacts Finely Stranded With Core End Processing":"1 ... 6 mm²"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/36ce5630bf4bcc5a8b06199b564b43cb.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=492946&mlfb=3RA2220-1AB23-0BB4"},"ai":{"faq":[{"question":"What are the key ratings of the 3RA2220-1AB23-0BB4?","answer":"It is a non-fused reversing motor starter, Size S0, rated for AC-3 duty up to 690 V at 50/60 Hz.
